AUBURN — Authorities on Friday continued their investigation into an armed robbery at Illini Bank in Auburn Thursday afternoon.

The FBI on Friday released two additional close-up bank surveillance camera images of the robber.

Auburn Police Chief Bruce Centko said no one was hurt and no shots were fired when the gunman entered the bank about 2 p.m. He left the area on foot with an undetermined amount of cash.

An Illinois State Police canine officer attempted to track the man. The FBI was also called to the scene.

“By the way the dog responded to the track, we believe the subject got into a vehicle and left,” Centko said.

Illini Bank is at 1311 W. Jefferson St. on the western edge of Auburn. That's adjacent to Illinois 4 and a little north of Illinois 104.

Centko said the location of the bank could have been a factor in the robbery.

Also, as a precaution, police notified the local schools.

“They held dismissal until we were done tracking and were reasonably positive the suspect had left the area in a vehicle. We did put units near the school when they were dismissing,” Centko said.

The robber was described as white, about 6 feet tall and weighing approximately 180 pounds. He was wearing a dark hoodie and had pulled the hood down over his face. He was also wearing a baseball cap, blue jeans and tennis shoes.

Centko said it's unusual for a bank in Auburn to be robbed.

“I've been the chief here for 20 years and this is the first bank robbery we have had,” he said.

Anyone with information on the robbery is asked to call Auburn police at 438-3351.
